我已經得到了循環依賴錯誤在我的佈局，我已經試圖找到任何循環依賴，但無法找到它，誰看到了？

java.lang.IllegalStateException：循環依賴不能在RelativeLayout的存在

Answer 1

錯誤在於以下組件

<Button 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Natureza" 
    android:id="@+id/btnNatureza" 
    android:onClick="btnPassearonClick" 
    android:layout_above="@+id/imageView2" 
    android:layout_marginBottom="10dp" 
    android:layout_toLeftOf="@+id/imageView11" 
    android:layout_toStartOf="@+id/imageView11" /> 

<ImageView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:id="@+id/imageView11" 
    android:layout_toEndOf="@+id/btnNatureza" 
    android:src="@drawable/passear" 
    android:layout_alignBottom="@+id/btnNatureza" 
    android:layout_toRightOf="@+id/btnNatureza" /> 

您指定btnNatureza必須要的imageView11權，但隨後你告訴imageView11它必須在btnNatureza的左邊。這是一個循環依賴，因爲這兩個視圖都沒有參考的起點，他們依靠彼此來確定它們的位置。爲了解決這個問題，您必須從Button或android:layout_toRightOf="@+id/btnNatureza"中刪除android:layout_toLeftOf="@+id/imageView11"ImageView

Answer 2

btnNatureza指imageView2是指imageView11是指btnNatureza

而且一般你不能說A是底部B和B在A以上。只保留一個。

<Button 
    android:id="@+id/btnNatureza" 
    android:layout_above="@+id/imageView2" 
    android:layout_toLeftOf="@+id/imageView11" 
    android:layout_toStartOf="@+id/imageView11" /> 

<ImageView 
    android:id="@+id/imageView11" 
    android:layout_toEndOf="@+id/btnNatureza" 
    android:layout_alignBottom="@+id/btnNatureza" 
    android:layout_toRightOf="@+id/btnNatureza" /> 

<ImageView 
    android:id="@+id/imageView2" 
    android:layout_toEndOf="@+id/imageView11" 
    android:layout_toRightOf="@+id/imageView11" /> 

Answer 3

這兩種觀點相互引用

<Button 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:text="Natureza" 
android:id="@+id/btnNatureza" 
android:onClick="btnPassearonClick" 
android:layout_above="@+id/imageView2" 
android:layout_marginBottom="10dp" 
android:layout_toLeftOf="@+id/imageView11" 
android:layout_toStartOf="@+id/imageView11" /> 

<ImageView 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:id="@+id/imageView11" 
android:layout_toEndOf="@+id/btnNatureza" 
android:src="@drawable/passear" 
android:layout_alignBottom="@+id/btnNatureza" 
android:layout_toRightOf="@+id/btnNatureza" />
